SPECIFICATION forming part of Letters Patent No. 768,023, dat d August23, 1904. Application filed September 27, 1902. Renewed December 31,1903. SerialNo. 187,387. (No model.)

To all whom, it may concern:

Be it known that I, LEONARD ANDRIEN, a citizen of the United States,residing atPhiladelphia, in the State of Pennsylvania, have invented anew and useful Printing-Press Attachment, of which the following is aspecification.

This invention is an improvement in printing-presses, and relatesparticularly to the class of presses adapted for printing yarn forpilefabric and also to the press or drum known to the trade as theGrilbert;- and the device relates particularly to an improved means foroperating the carriage.

Heretofore the carriages, and especially the Gilbert, have beenoperated'by cables which are connected at one end to the ends of thecarriages and at their opposite ends to a segment which is operated byclutch and gear wheels for reciprocating the carriage along the bed ofthe press. tion has been found most objectionable for the reason thatthe cord or cable invariably stretches and often breaks, in either casecausing the press or drum to be stopped, which causes the loss of muchvaluable time and labor.

It is therefore the object of my invention to eliminate theseobjectionable features and to provide a device by which the length oftravel of the carriage may be so regulated that the same will be assuredthrough the entire operation of the press. r Y

With these briefly-stated objects in view my invention consists incertain details of construction and novelties of combination andarrangement, as will be fully described in the following specificationand pointed out in therying a cylinder or drum B, all of which being ofthe usual constructions and for that reason shown only in diagram.Suitably journaled in the post A is a short shaft C, carrying This meansof opera' a sleeve D, from which depends an arm D,

and to the lower end of this arm is secured one end of the pitman D itsopposite end being pivotally connected to the ordinary carriage E, asshown most clearly in Fig. 1 of the drawings. The shaft 0 also carries acollar C, from which runs crank-arm F, to which is connected a pitman orlink-bar G, which is also pivotally connected to and carried by agear-wheel H, journaled in any suitable manner at the side of the drumB. The said gear H, is driven by a pinion H, arranged upon a shaft Hwhich shaft also carries a pulley H over which runs a belt H,

.that may be driven in any suitable manner from an adjacent shaft. Thisshaft H may be supported in any convenient manner. The shaftC alsocarries an arm I, having a counterbalance-weight I formed 1 integraltherewith, as shown most clearly in Fig. 2 of the drawings. In practiceI may find it advisable to secure an arm and weight to the opposite sideof the drum to act as a balance for improvement willreadily appear tothose skilled in the art to which it appertains, and

' it will be particularly noted that the operation of the carriage ispositive, that it will be moved a certain distance at each movement ofthe arm, and,further, that there are no parts to get out of order, thusassuring a more perfect operation or feed of the carnage than 1s securedby the mechanism now generally em-' ployed. I desire to state, further,that the sleeve may be dispensed with and the depending arm, crank, andweight-arm cast upon a short shaft, that may be journaled in anysuitable manner adjacent the drum, and also that minor changes may bemade without departon, collars rigidly secured to the irst-mentionedshaft on each side of the sleeve, an arm I 5 secured to the innercollar, a crank member pivotally secured at one end to the gear and atthe other end to the last-mentioned arm, a Weighted arm secured to theouter collar and on the side of the carriage, and means for 20 drivingthe gear.

LEONARD ANDRl EN.
